Direct Observation of NF(X) Using Laser-Induced Fluorescence: Kinetics of the NF 3 Sigma(-) Ground State

Abstract

Vibrational relaxation of NF(X) produced from the 249 nano m photolysis of NF2 was investigated with CO2 and SF6 as the quenching partners. State-to-state vibrational quenching rate constants were obtained for NF(X, v' = 1-3). SF6 is seen to be an efficient vibrational quencher of NF(X), while CO2 is relatively inefficient, contrary to what is observed for HF vibrational relaxation. The bimolecular disproportionation of NF(X) is seen to be much smaller than previously reported, while the reaction of NF(X) with NF2 is surprisingly fast and may be the dominant removal mechanism for NF(X3 Sigma).
